FAQ
Eavestrough questions, answered.
What areas does Goodflow Eavestrough serve?
We serve Cornwall and the United Counties of Stormont, Dundas and Glengarry (SDG) in Eastern Ontario, including Long Sault, Ingleside, Morrisburg, Winchester, Alexandria, Lancaster and nearby communities.
What is a seamless eavestrough?
A seamless eavestrough is formed on site from a continuous length of aluminum, measured to your roofline. With no joints along each run, there are fewer places for leaks to start and the finish looks cleaner.
Do you repair and clean existing eavestroughs?
Yes. We fix leaks, loose or sagging sections and blocked downspouts, and clean out debris so water drains away from your home properly.
Are leaf guards worth it in SDG and Cornwall?
For homes near mature trees, leaf guards cut down on clogs and cleanings by keeping leaves and debris out of the eavestrough while letting water through.
